 * Data filtering and deduplication:

+    * Web data has been filtered to minimize potentially toxic content and personally identifying information. 
 * Ethics:
     * Special care has been taken to respect copyright laws and individual privacy.
-      All books, newspapers, monographies, and magazines are in the public domain

-### Dataset Structure
+### Sample Metadata
 
-The corpus contains the following information for each text sample:
-* `text`: the text sample itself.
-* [`language`](metadata/metadata_examples.json#L3): the language of the text sample (relying on the source, that information can be wrong).
+In addition to the `text` field, which provides the content of the sample, each training sample in the corpus contains the following metadata when available:
+* [`language`](metadata/metadata_examples.json#L3): the language of the text sample (note that this information is taken from the original data source and may be incorrect).
   <br>Possible values:
-  - an ISO 639-1 code of a natural language ("en", "fr", "de", "es", or "it"),
-  - a common name prefixed by "code:" of a programming language ("code:python", "code:c++", …), or
-  - a list of ISO 639-1 codes separated by commas when the text sample is multilingual and aligned ("fr,en", "de,fr", "es,en", "it,en",
+  - the ISO 639-1 code for a given natural language ("en", "fr", "de", "es", or "it"),

   or one of those pairs in the opposite order if the languages appear in the opposite order in the text).
 * [`source`](metadata/metadata_examples.json#L4): an identifier for the source(s) of the text sample (Wikipedia, RedPajama, Gutenberg, …).
-  All sources are described in detail [in this document](#details-on-data-sources).
-* [`id`](metadata/metadata_examples.json#L13): an identifier that is unique among the source.
+  All sources are described in detail [below](#details-on-data-sources).

 * [`title`](metadata/metadata_examples.json#L36) (optional): the title of the original text sample, if available.
 * [`author`](metadata/metadata_examples.json#L81) (optional): the author of the original text sample, if available.

OPUS pairs were passed through a custom pipeline designed to select the highest quality sentences pairs. Selected pairs are labeled "UnbabelFrEn" in the CroissantAligned dataset. The thesis abstract subset contains pairs of French or English thesis abstracts paired with translations written by the thesis author. The song lyrics are translated by contributors to www.lacoccinelle.net. Parallel data are used to boost the multilingual capabilities of models trained on them ([Faysse et al.,2024](https://arxiv.org/pdf/2402.00786)).
-* <u>Text Pre-processing</u>:
-  * <u>Language Separation and Tagging</u>: The original text field of [the Croissant dataset](https://huggingface.co/datasets/croissantllm/croissant_dataset_no_web_data) includes both French and English passages in a non-deterministic order (sometimes English first, sometimes not), separated by different delimiters depending on the subset.
-  Each text was split into monolingual sentences and tagged with the appropriate language code, identified automatically using the [langid library](https://pypi.org/project/langid/).
-  These texts are provided separately in the Lucie-Training-Dataset under the extra field as text_fr for French and text_en for English.
-  * <u>Random combination of texts prefixed by language</u>: The monolingual texts were recombined using random separators and various methods of prefixing the text with the language (name or code).
-  This was done as a precaution to prevent models trained on this data from language switching when generating text.
-  It can be seen as a very basic instruction to translate the first text into the other language.

+* <u>Description</u>: CroissantAligned contains samples of parallel French/English (or English/French) data. Data extracted from OPUS takes the form of sentences pairs, where one sentence is in French and the other is in English. OPUS pairs were passed through a custom pipeline designed to select the highest quality translation examples. Selected pairs are labeled "UnbabelFrEn" in the CroissantAligned dataset. The thesis abstract subset contains thesis abstracts paired with translations written by the thesis authors. The song lyrics are translated by contributors to www.lacoccinelle.net. Parallel data are used to boost the multilingual capabilities of models trained on them ([Faysse et al.,2024](https://arxiv.org/pdf/2402.00786)).
+* <u>Pre-processing</u>:
+  * <u>Language separation and tagging</u>: The original text field of [the Croissant dataset](https://huggingface.co/datasets/croissantllm/croissant_dataset_no_web_data) contains a sentence or passage in French or English immediately followed by its translation without any indication of which passage is in which language. The first step was thus to split each text into separate, monolingual passages and tag each passage with the appropriate language code, identified automatically using the [langid library](https://pypi.org/project/langid/) (see [code details](https://github.com/OpenLLM-France/Lucie-Training/blob/cdec8fd6369385455829ab39c2f04bcb1a8a475a/tokenization/data.py#L1407)). In the Lucie Training Dataset, the `extra` metadata field for CroissantAligned contains separate keys, `text_fr` for French and `text_en` for English, that stores the texts separately.
+  * <u>Random combination of texts prefixed by language</u>: To create the text values, each monolingual text was repaired with its translation, but random separators and various methods of prefixing the text with the language (name or code) were added.
+  This was done as a precaution to prevent models trained on this data from switching languages when generating text and can be seen as a very basic instruction to translate the source (first) text into the target (second) text (see [code details](https://github.com/OpenLLM-France/Lucie-Training/blob/cdec8fd6369385455829ab39c2f04bcb1a8a475a/tokenization/data.py#L1458)).

 * <u>Description</u>: A collection of doctoral theses published in France. Dataset containing text retrieved through OCR.
-* <u>Text Pre-processing</u>:
-  * <u>Filtering</u>: Text with less than 1000 words or 10000 characters were removed.
-  * <u>Text cleaning</u>: Because the results of OCR on tables and graphics can give raise to garbage text, the text was cleaned by removing the most suspicious chunks of text. Chunks of text were removed if the detected language was not among French, English, Spanish, German and Italian, or if the perplexity of a CCNet Language Model was higher than 2000 ([details here](https://github.com/OpenLLM-France/Lucie-Training/blob/7f1f7efa1288f709662a9067bf2c3db856b850f8/tokenization/data.py#L1946)).

+  * <u>Text cleaning</u>:
+    * Title pages about HAL, pages containing a significant fraction of control characters, and duplicate lines were removed (see [code details](https://github.com/OpenLLM-France/Lucie-Training/blob/cdec8fd6369385455829ab39c2f04bcb1a8a475a/tokenization/text.py#L277)).
+    * Because the results of OCR on tables and graphics can give rise to garbage text, the text was cleaned by removing the most suspicious chunks.
+    In particular, a chunk was removed if it was not detected as being written in French, English, Spanish, German or Italian, or if the perplexity of a CCNet Language Model on the chunk was higher than 2000 (see [code details](https://github.com/OpenLLM-France/Lucie-Training/blob/7f1f7efa1288f709662a9067bf2c3db856b850f8/tokenization/data.py#L1946)).
